CUES 口令
Starting position: Prone on floor in front of chair, hands on pedals, arms extended. Breathing: Inhale to extend spine upward to comfortable height; exhale to roll body down to start, allowing pedals to rise. Imagery: Body like a swan spreading wings on water.
预热：Prone Press Up & Swimming-M（髋伸预热不求高，求的是向后的延伸感）;【起始位】俯卧在万能椅前方的地板上，双手放在踏板上，手臂延伸。 【呼吸】吸气时将脊椎伸展后仰直到舒服的高度（保持最下段的肋骨在垫子上）同时把踏板往下压；吐气将身体往下卷回到起始姿势，同时让踏板升高；必要时可以调整呼吸方式，吐气时往下压，以改善肩胛的稳定度；踏板不必压到底。 【想象】身体像一只在水面舒展翅膀的天鹅。
IMAGERY 意象
【Direct】Inhale to prepare, extending the crown of the head away to increase spinal length. On exhale, recruit deep abdominals to pull the navel toward the spine, providing support for the lumbar region. Use the downward pressure of the hands on the pedal to guide the spine in articulating segmentally off the floor, keeping shoulders depressed and widened. 【Indirect】Smiling Collarbones: Imagine your collarbones are flashing a brilliant, wide smile; this instantly helps open the chest and stabilize the scapulae. Pearl Necklace Articulation: Feel your spine as a string of expensive pearls; as the movement begins, each pearl moves elegantly and independently. Helium Balloon Traction: Imagine your head as a helium-filled balloon, lightly drifting upward and taking your cervical spine with it. 【Space】Elbows Reaching Back: While supporting, imagine your elbows reaching for the wall behind you, using this spatial cue to facilitate deeper thoracic extension. Gaze into the Distance: Lock your eyes onto a fixed point far away, using the physical extension of your gaze to guide the body into a grander space. Expanding into the Void: As you push up, feel your chest entering a transparent, vast vacuum rather than being compressed by the equipment. 【Feeling】Peeling Velcro (Tactile): As you roll up, feel the spine peeling away from the floor like Velcro, separating segmentally with a distinct sense of rhythm. Thick Syrup Damping (Kinesthetic): Imagine pushing the pedal through thick syrup, ensuring both the descent and ascent are uniform, deep, and controlled. Cloud-like Floating (Proprioception): As the pedal returns, feel a lightness in the back as if it’s floating upward, as though the constraints of gravity have vanished.
【直接】吸气准备，头顶向远处延伸以增加脊柱长度。呼气时，募集深层腹肌将肚脐向脊柱方向收缩，为腰椎提供支撑。通过双手下压踏板的力量，引导脊柱由颈椎开始一节一节地从地面向上卷起，同时保持肩膀下沉并向两侧放宽。【间接】锁骨的微笑：想象你的锁骨正在展现一个灿烂、宽阔的微笑，这能瞬间帮你打开胸腔并稳定肩胛骨。珍珠项链的分节：感觉你的脊柱就像一串昂贵的珍珠项链，随着动作的开启，每一颗珍珠都在优雅地、独立地移动。氦气球牵引：想象你的头颅是一个充满了氦气的气球，正轻盈地带着你的颈椎向上方飘浮。【空间】肘尖够向后方：在支撑时，想象你的手肘正努力够向身后的墙壁，通过肘部的空间导向来辅助胸椎的深度伸展。视线射向远方：让你的目光锁定远处的一个固定点，通过视线的物理延伸引导身体进入更宏大的空间。扩张进入真空：在向上推起时，感觉胸部正在进入一个透明且宽阔的真空区域，而非被器械压缩。【感觉】剥离魔术贴（触觉）：向上卷起时，感受脊柱像撕开魔术贴（Velcro）一样，带着清晰的节奏感一节一节从地面分离。厚重糖浆的阻尼（动觉）：想象你正在浓稠的糖浆中推动踏板，确保下压与回升的过程均呈现出匀速、深沉且受控的质感。云端的悬浮感（本体觉）：在踏板回弹时，感受背部有一种向上漂浮的轻盈感，仿佛重力的约束正在这一刻消失。
TACTILE CUES 触觉提示
Hand on thoracic spine to guide extension; lightly press inferior angle of scapulae to prevent shrugging; remind to maintain length in lumbar spine.
手置于胸椎段引导伸展；轻按肩胛下角防止耸肩；在腰椎处提醒保持长度。
PROGRESSION 进阶
P- vary angle of spinal extension; P-Add variations with spine and head rotation, pressing down into the direction of the slightly bent arm；P- add contralateral leg lift (rotate right/lift left leg).
P-改变脊椎伸展后仰的角度；P-可加入脊椎和头旋转，往下压微弯的手臂方向的变化；P-加上对侧边的腿抬起（往右旋转/抬左腿）。
REGRESSION 退阶
R- do not need to press pedals fully; R- place a long box under body to reduce joint flexion angle.
R-踏板不一定要压到底；R-放长盒子在身体下方减少关节屈曲角度。
COMMON ERRORS 常见错误
Inadequate shoulder range; shoulder shrugging; insufficient thoracic extension/using lumbar push; overusing hip muscles; excessive cervical extension.
适当的肩关节活动范围不足；耸肩；胸椎后仰伸展不足/用腰椎前推；臀肌过度用力；颈椎过度伸展后仰。
PRECAUTIONS 注意事项
